Besides the Symmetricom SA22c unit which can be found here :


There is also the Frequency Electronics Inc. unit FE-5650 which is very much the
same size and can be found here :


The SA22c is .91" high by 3.0x wide and 4.4x long.  In contrast the FEI unit is
1.4" high by 3.03" square.  So take your pick !

The SA22c has additional options that the FEI does not have like external 1pps
sync input for connection to a GPS and RS232 communication port for enhanced data
between the SA22c and your computer.

I guess it depends upon what you need it for.
